(flake->pred-map flakes)lang-sid->langclj/s
new-pred-changesclj/s
(new-pred-changes db tempids flakes)Returns a map of predicate changes with their respective old value and new value, both the key and value of the map are two-tuples as follows: {subid {:new? true :type {:old :int :new :long} :index {:old nil :new true }}}
If the predicate being changed is the :type, it resolves the type _tag to its short keyword name
When an old value does not exist, old-val is nil. If they subject being created is completely new, :new? true
Returns a map of predicate changes with their respective old
value and new value, both the key and value of the map are two-tuples as follows:
{subid {:new? true
:type {:old :int :new :long}
:index {:old nil :new true }}}
If the predicate being changed is the :type, it resolves the type _tag to its short keyword name
When an old value does not exist, old-val is nil.
If they subject being created is completely new, :new? true pred-name->keywordclj/s
(pred-name->keyword pred-name)Takes an predicate name (string) and returns the namespace portion of it as a keyword.

(pred-objects-unique? db pred-id)pred-reverse-ref-reclj/s
predicate-change-errorclj/s
(predicate-change-error pred-changes db)(predicate-change-error pred-changes db throw?)Accepts a db (should have root permissions) and a map of predicate changes as produced by new-pred-changes. Returns a db with updated idxs if relevant, i.e. if non-unique predicate converted to unique If optional throw? parameter is true, will throw with an ex-info error.

(reverse-ref predicate-name)Reverses an predicate name.
Reverses an predicate name.
reverse-ref?clj/s
(reverse-ref? predicate-name)(reverse-ref? predicate-name throw?)Reverse refs must be strings that include a '/_' in them, which characters before and after.
Reverse refs must be strings that include a '/_' in them, which characters before and after.
schema-mapclj/s
(schema-map db)Returns a map of the schema for a db to allow quick lookups of schema properties. Schema is a map with two keys:
- :coll - collection info, mapping cid->name and name->cid all within the same map
- :pred - predicate info, mapping pid->properties and name->properties for quick lookup based on id or name respectively

(version db)Returns schema version from a db, which is the :t when the schema was last updated.
